I've started a couple families, made sure they both definitely want kids, but they won't have any! They just argue whenever I try. Now they're in their late 30s, almost 40! Are there some pre-existing conditions that have to happen first? Do they need a certain amount of money in the bank? It takes forever to generate the kind of person I want (I'm very picky - must be red-headed woman who wants a large, large family) and match (must be a blond male who also wants a large family). By the time they marry, they're in their 30s. Can someone help? Please???
